Lake Lienia.
As the only region within the Sain Dungeon where people can reside permanently, it cannot be compared with other regions when discussing which is the most popular.
Because if there's a Lake District, people would surely choose it.
Apart from its convenience and the ability to learn magic, due to the large map and the highly random resources, even a regular person can wander around and have a chance to escape danger and bring back some treasures.
If one could open a shop in each safe zone, even selling food could make money, as adventurers always have various needs.
As the center of Lake Lienia, Reyalucaria Magic Academy is naturally a popular map. People believe that this academy could be a standalone region, proving just how vast the Lake District is and how rich in content.
